FILTER.

Application filed June 5,

My invention relates to improvements in filters, and particularly filters of the type adapted for household use wherein water is filtered through a candle or filter cup made of infusorial earth or diatomaceous earth and has for one object to provide a new and improved form of filter which will be compact, satisfactory in operation, which Wlll be more durable, easier to manufacture and wherein the renewal of the filter candle will be easy and convenient. Other objects Wlll appear from time to time in the specification and claim.

My invention is illustrated more or less diagrammatically in the accompanying drawings, wherein:

Figure 1 is a side elevation;

Figure 2 is a plan view;

Figure 8 is a section along the line 3-3 of Figure 2;

Figure 4 is a rear elevation in part section along the line 4l-4 of Figure 2.

Like parts'are indicated by like characters throughout the specification and drawings.

A is the ordinary type of water cock such as is found in residences having the valve handle A to control the flow of water and terminating in a threaded discharge mouth A A is a valve housing having a dis charge spout A in line with the threaded discharge mouth A A is a holding sleeve threaded in the housing A flanged at A to overlie an inwardly extending shoulder A on the threaded collar A A is apacki g ring carried by the sleeve A? and adapted to engage the end of the discharge cock or mouth A", when the ring A is screwed on the mouth portion A to hold the parts firmly together. A is a two-way valve mounted in the housing A controlled by a handle A so arranged that in various positions it can turn oil the flow of water altogather or may direct it through the discharge openin i- 4 or through the filter as the case may be.

B is a bed plate mounted on the hollow arm B which projects laterally from the housing if, there being awater passage 13" within the hollow arm communicating with the valve A The bed plate B is provided with an upwardly extending flange B exteriorly threaded. B* is a filter housing thread ed to engage the flange B is a packing adapted to be compressed between the edge of the housing and the periphery of the plate B. B B, are corrugations on the base 1924.

of the housing, whereby it may be rotated to screw it up, tightly compressing the packing B and making a liquid tight joint. This housing B is bell shaped and provides a. sufiicient water tight chamber on the outside of the candle.

C is a hollow filter candle of infusorial earth or other material. It is mounted on an impervious base C C is a support upon which the candle base C- may be firmly mounted. This support is held in position by the tube C which extends downwardly therefrom through an aperture in the center of the bed plate B. This tube is threaded and a locking nut C engages it to hold the tube and the member C firmly in position and prevent escape of water from the housing. C is a discharge spout from the filter. The fact that the member C is held down firmly against the bottom of the base makes it impossible for the leakage of water without passing through the infusorial earth material. The combination of the reduced member C with the enlarged member C and the relatively narrow annular passage D between the member C and the flange B provides a channel around thebase of the filter cavity fed by water or other liquid from the passage 13 thus insuring that the liquid will pass up on all sides of the candle from the bottom. Since the total cross sectional area of the annular channel D and the space between the filter housing and the candle is very considerable with respect to the amount of water flowing through, sedimentation will be easy and any large particles of foreign matter which enter the system will tend to concentrate at the bottom rather than deposit on the filter area, thus leaving the filter area free to perform its intended function merely to separate the finestimpurities from the water. Of course, when the filtering surface becomes clogged up the housing may be removed and the filtering candle cleaned and this can be done with minimum of difliculty because the removal of the housing and the candle may be performed without in any way interfering with the attachment of the apparatus to the faucet.

I claim:

A filter comprising a supporting base, a hollow filter candle mounted on and projecting thereabove a discharge nozzle leading from the interior of the candle through the base, means associated with the nozzle for holding the candle in position on the base,

the discharge line of the nozzle being in downward prolongation of the central axis of the candle, a housing mounted on and projecting upwardly from the base surrounding the candle, a liquid passage discharging through the base into the space be tween the candle and the housing around the lower periphery of the candle, a water pipe communicating therewith, a connection carried thereby adapted to engage a Water supply tap and a three-way valve adapted when in one position to permit direct discharge of water without passing through the filter and when in another position to direct water through the filter.
